Gemma Chan has revealed she has the final say on any jokes boyfriend Jack Whitehall wants to make about her and their relationship.

The 30-year-old actress - who has starred in Secret Diary Of A Call Girl, Doctor Who, Sherlock and Channel 4 comedy Fresh Meat, where she met Jack - opened up to ES magazine and said it can be hard dating a comedian.

Gemma said: "It's a persona he plays on stage; it's a heightened, exaggerated version of him.

"As a comedian you use your own life but I think people know it's not a literal telling of the truth. You appropriate stories and present them as something that happened to you.

“If he wants to draw on my life, it's on a case-by-case basis. He knows he has to run everything by me first."
